Which characteristic is a property of molecular substances?
(1) good heat conductivity(2) good electrical conductivity(3) low melting point(4) high melting point

Option (3) is the correct answer.

Explanation:

Molecular substances are the substances which have two or more different atoms attached together.

Molecular substances have weak intermolecular forces of attraction thus, they have low melting and boiling point.

They have poor electrical conductivity as the bond formation in molecular compounds is covalent. Therefore, they also have poor heat conductivity.

Hence, out of the given options low melting point is the characteristic property of molecular substances.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
